Plastic steel profiles have become a major component in the construction industry in China, with large-scale production starting as early as 1995 when Dalian Shide Group first utilized them for plastic steel doors. The country's annual production capacity for these profiles has now reached an impressive 5 million tons. However, this growth has led to significant overproduction and intense competition among similar products. Among the leading companies, Wuhu Conch Profile Co., Ltd. holds the largest production scale, followed by Dalian Shide, Zhejiang Zhongcai, Hebei Baoding Baoshuo, Shandong Jinda Shuangpeng, and Shanxi Zhongde.
The national standard for plastic steel profiles in China is GB/T 8814-2004, which many manufacturers follow, even those that have obtained national exemptions. Unlike in Europe and the United States, where a wider variety of profile types are available, China's market is dominated by just a few standard designs. Most of the profiles currently in circulation are 60mm flat door and window profiles and 80mm sliding door and window profiles, which together make up more than 80% of total consumption. This limited variety reflects the industry’s focus on mass production rather than innovation or customization.

The country's annual production capacity for these profiles has now reached an impressive 5 million tons. However, this growth has led to significant overproduction and intense competition among similar products. Many companies are struggling to differentiate themselves, resulting in a saturated market with low profit margins. Among the leading companies, Wuhu Conch Profile Co., Ltd. holds the largest production scale, followed by Dalian Shide, Zhejiang Zhongcai, Hebei Baoding Baoshuo, Shandong Jinda Shuangpeng, and Shanxi Zhongde.
The national standard for plastic steel profiles in China is GB/T 8814-2004, which many manufacturers follow, even those that have obtained national exemptions. This standard ensures basic quality and performance requirements, but it also contributes to the homogenization of products. Unlike in Europe and the United States, where a wider variety of profile types are available, China's market is dominated by just a few standard designs. Most of the profiles currently in circulation are 60mm flat door and window profiles and 80mm sliding door and window profiles, which together make up more than 80% of total consumption. This limited variety reflects the industry’s focus on mass production rather than innovation or customization. As a result, many companies are looking for ways to add value through improved design, energy efficiency, or eco-friendly materials to stand out in a crowded market.
